Certainly well named as it not only attracts large quantities of butterflies but is also just as attractive to hummingbirds. Honeybees and Bumble bees are also very attracted to the flowers. I have to prune my butterfly bushes back strongly in early spring to keep them from growing excessively large. They bounce back from the pruning immediately with new growth.

Honey bees get nectar from this plant.

Many of the modern cultivars of Buddleia davidii have dramatically reduced fertility and are not invasive at all. Many hybrid cultivars (such as ‘Blue Chip') are almost completely sterile and pose no threat. Some low viability selections include, Buddleia ×weyeriana, Buddleia fallowiana, Buddleia hemsleyana, Buddleia longifolia, Buddleia macrostachya, and Buddleia nivea.

This is an escaped invasive in Washington, and is on the Class B noxious weed list. There are more and more sterile cultivars being offered, which would be a wiser choice where this plant has overstayed its welcome.

Butterfly Bush (Buddleja davidii) is a deciduous, perennial shrub growing to 6' in height and to 15' wide, with arching branches and clusters of blooms that form a weeping habit when the bush is full. Buddleja is drought tolerant once established and prefers a full to partial sun location. Flowers come in various shades of red, pink, purple, and white and attract a wide range of butterflies to the garden.

This plant grows so well in Kentucky, blooms through fall if deadheaded. It provides a nice backdrop since it can grow quite tall. I also have the plant in white, but it seems the blue/lavender gets more insect traffic.

In Southeast England, these often grew out of old walls!
